Oxbox J5GXCA003AC6HU Upflow Downflow Cased Evaporator Coil 1.5 to 3.0 Ton R-454B

Product Description

The Oxbox J5GXCA003AC6HU is a cased evaporator coil rated for 1.5 to 3.0 tons of cooling capacity and designed to operate with R-454B refrigerant, a next-generation A2L refrigerant replacing R-410A in new residential split systems. The coil ships in an upflow and downflow configuration, giving installing technicians the flexibility to fit it into a range of air handler and furnace installations. Oxbox is a Trane brand built to deliver dependable performance at an accessible price point, making this coil a straightforward OEM-style choice for residential cooling applications requiring R-454B compatibility.

This coil is suited for residential split-system air conditioning installations where the indoor unit is positioned in an upflow or downflow orientation. It is designed to pair with matched outdoor condensing units using R-454B refrigerant. Based on available bundle data, it has been matched with the Oxbox J5AC5018A1000 1.5-ton condenser in a confirmed system pairing. Typical installation scenarios include replacement of an existing evaporator coil in a forced-air system or new construction installations requiring R-454B-compatible indoor coil equipment.

Key Features

• Compatible with R-454B (A2L) refrigerant — required for new residential split-system installations under current EPA guidelines
• Covers 1.5 to 3.0 ton capacity range, reducing inventory SKU count for contractors stocking multiple system sizes
• Upflow and downflow configurable — fits a wider range of residential air handler and furnace pairings
• Cased design provides a factory-finished enclosure, simplifying installation and sealing around the coil cabinet
• Oxbox by Trane lineage means parts, documentation, and service support are aligned with a major OEM network

Compatibility

Confirmed in a matched system pairing with the Oxbox J5AC5018A1000 1.5-ton R-454B condenser. Designed as an OEM-style replacement or new-install evaporator coil for residential upflow and downflow split-system configurations using R-454B refrigerant. Verify system tonnage and refrigerant compatibility before installation.

Installation Notes

Installation of this evaporator coil must be performed by an EPA Section 608 certified HVAC technician, as R-454B is an A2L mildly flammable refrigerant requiring specific handling procedures and leak detection practices. Power down and disconnect all electrical service to the air handler or furnace before beginning coil replacement. Confirm that all system components — including the line set, metering device, and outdoor unit — are rated for R-454B service before commissioning. Follow local mechanical codes and the manufacturer installation instructions for proper drain pan connection, refrigerant line flaring, and leak testing procedures.
